XLR Connectors
Below is the Pin configuration for the XLR Balanced Input
Connectors on the MA6600. Refer to the
diagram for connection:
PIN 1: Shield/Ground
PIN 2: + Output
PIN 3: - Output
Power Control Connector
The MA6600 Power Control Output Jack sends Power On/
Off Signals when connected to other
McIntosh Components. A 1/8 inch
stereo mini phone plug is used for con-
nection to the Power Control Output
on the MA6600.
Note: The Data and Power Control Connecting Cable is avail-
able from the McIntosh Parts Department:
Data and Power Control Cable Part No. 170-202
Six foot, shielded 2 conductor, with 1/8 inch stereo mini
phone plugs on each end.
Data Port Connectors
The MA6600 Data Out Ports send Remote Control Signals
to McIntosh Source Components. A 1/8
inch stereo mini phone plug is used for
connection.
McIntosh Plug-In Jumper Connector
The MA6600 utilizes a phono style Plug-In Jumper to con-
nect the OUTPUT 1 (Preamplifier Output)
Jack to the PWR AMP (Power Amplifier
Input) Jack for each channel.
Note: The Jumper Connector is available
from the McIntosh Parts Department:

• Power Output with Patented Autoformer
The MA6600 consists of a 200 watts per channel stereo
Power Amplifier with less than 0.005% distortion. The
McIntosh designed and manufactured Autoformer allows
connection of 2, 4 or 8 ohm Loudspeakers. The Power
Amplifier uses Thermal Trak
1
Output Transistors for lower
distortion and cool operation.
• Electronic Switching and Balanced Connections
The Preamplifier uses Logic Circuits controlling Electro-
magnetic Switches on all inputs and operating functions
for reliable, noiseless, distortion free switching.
There is a
Balanced Input for connection of source components.
• Power Guard
The patented McIntosh Power Guard circuit prevents the
amplifier clipping and protects your valuable Loudspeak-
ers.
• Multifunction Fluorescent Display
The Front Panel Display indicates source selection, volume
levels, tone adjustments, setup functions and tuner func-
tions when the optional Tuner Module
2
is installed.
• Illuminated Power Meters
The Illuminated Power Output Watt Meters on the
MA6600 are peak responding, and indicate the power out-
put of the amplifier.
• Power Control and Remote Control
The Power Control Output connection provides convenient
Turn-On/Off of McIntosh Source Components. The Data
Ports together with the supplied Remote Control provides
control of McIntosh Source Components connected to the
MA6600.
• Special Power Supply
The large Power Transformer, multiple filter capacitors
with 100 Jules of Energy Storage and regulated Power
Supply ensures stable noise free operation even though the
power line varies.
• Fiber Optic Solid State Front Panel Illumination
The even Illumination of the Front Panel is accomplished
by the combination of custom designed Fiber Optic Light
Diffusers and extra long life Light Emitting Diodes
(LEDs). The glass Front Panel ensures the pristine beauty
of the MA6600 will be retained for many years.
Now you can take advantage of traditional McIntosh stan-
dards of excellence in the MA6600 Integrated Amplifier.
The Power Amplifier section of the MA6600, with a power
output of 200 watts per channel, will drive a pair of quality
Loudspeakers to a high level of performance. The flex-
ible Preamplifier section provides connections for various
input sources and may also be used to drive an external
Power Amplifier. The MA6600 reproduction is sonically
transparent and absolutely accurate. The McIntosh Sound
is “The Sound of the Music Itself.”
